You have to see it from the bankers point of view. First you talk them all into financing a house,car maybe even a boat, you set them all up with credit cards. Then if you wait and let them pay you the down payments and the notes for several years and "crumble the economy", you have all the money they gave you in the down payments and notes.
Now if you take the down payments and notes and don't crumble the economy then the people will pay those properties off and they will own them and not you. So but if you let them string themselves out into usury
https://en.wikipedia.org/wiki/Usury and you reposes all the property and goods then you have made the money they paid you plus you still own the things you repossessed and you can begin again selling it to them.
Then so first you have to promise to fix the economy year after year to give them confidence to buy those things and obtain that credit. Then you wait for whichever calamity to come along to so that it will not seem as though it's you who is to blame. You pretend you are fixing the economy when that was never the thing you were intending to do if you see it from the bankers point of view it was always to crumble it and keep the things and all the money.
